Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Wind-sheltered terrain continues to offer excellent riding conditions. Wind slabs linger near ridgetops and in cross-loaded terrain features.

Confidence

Moderate

Avalanche Summary

A size 2 natural wind slab avalanche was reported on Sunday; in northerly alpine terrain near a ridgetop.

If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Unconsolidated powder snow continues to be found in wind-sheltered terrain. While recent northerly winds have heavily affected snow surfaces in wind-exposed terrain at treeline and above.

An old crust is present down roughly 40 to 80 cm from the surface. In isolated areas, the overlying snow may not be bonding great to this crust.

The lower snowpack consists of several layers of facets, surface hoar, and crusts, none of which appear to be an active concern currently.

Weather Summary

Monday Night

Mostly clear with no precipitation, northwest alpine winds 0 to 20 km/h, treeline temperature -5 °C.

Tuesday

Mix of sun and cloud with no precipitation, west alpine winds 0 to 20 km/h, treeline temperature -9 °C.

Wednesday

Cloudy with 5 to 10 cm of snow, southwest alpine winds 10 to 30 km/h, treeline temperature -15 °C.

Thursday

Mostly cloudy with no precipitation, south alpine winds 10 to 30 km/h, treeline temperature -12 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Seek out sheltered terrain where new snow hasn't been wind-affected.
  • Approach lee and cross-loaded slopes with caution.
  • Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
